I hate that this is true. I've posted here before on the same topic[1] and although we know a lot of stuff about computers, we don't really grok them. Or at least, not a lot of my peers do, and I'm sorely missing some info myself. My friends just don't care. At all. About anything related to lower level computing. I explain things and they ignore me, even when I try to make it relatable (without being patronizing). I'm glad I'm not a teacher because I don't know how to get people interested in what I'm interested in.
